Today I will tell you about a project
that took a month of daily work, hundreds of sensors, a
thousand connections, a lot of difficulties
and problems. And as a result, a smart countertop,
analogues of which I haven't seen. Enjoy watching. So, we proceed to making a
table consisting of honeycombs. In general, such tables have
already been made by dozens or even hundreds of
craftsmen before us. And in general, there is a legend that
every self-respecting epoxy craftsman should pour a table of
honeycombs. We started this, but decided to
go a little further and make such a table with
smart filling, but first things first. The countertop will be made
of oak, and, as you understand, the frames of Andrei preparing
oak boards are not accidental here. We will make a
shield out of them. First, we pass them
through the jointer, and then we bring them to
the same size using a planer. When all the boards
are in the same size, we are gluing them together. Here everything is simple:
boards, glue and clamps. While you are watching the work, I
want to tell you about one cool thing that appeared back in the summer
of 2020 and instantly became a hit. This is Mozabrik - an
endless photo constructor. That is, from small elements of the
constructor of five colour gradations, you can assemble any
photo in the style of pixel art. And when you get bored - disassemble
and assemble any other picture. This is done very simply, and the
result is guaranteed to cause a wow effect. How it happens: You buy
a constructor, go to the site, upload a photo and
choose the layout you like. You will immediately receive
assembly instructions by mail, or proceed to assembly
according to the interactive instructions
immediately on the site. And from 5 colours you
can assemble any image. I myself gladly assembled
such a picture in one of the previous videos
and was really delighted. I will leave a link to that
video in the description. Mozabrick.ru is the official website
and online store of the manufacturer. They are produced,
by the way, in Russia. You can choose from
two sizes - S and L. The constructor is suitable
for all ages and any gender, making it a cool
gift for any occasion. Moreover, according to my promo
code, you will receive a 20% discount. You will find the link and promo code
in the description, and we continue. The next day the glue is dry
and I put the shield on the CNC. I fix it with a vacuum,
probably for many it will be news that the vacuum table works through
MDF, and the workpiece is held tightly, which I demonstrate
in the frame. Personally, I was very surprised
when I found out this feature. Well, then a few
hours of CNC work, the program is set
up in such a way that it does not cut the
honeycombs to the end, quite a bit, so that they remain
strictly in their places. As a result, we have
just such an apiary, which I polish before
pouring it with epoxy. Otherwise, the pile and shavings will
remain in the fill forever, oddly enough. The next step is to remove
some of the honeycomb solely by my own
taste or lack thereof. I would like to read about
this in the comments. When all the necessary, or rather
unnecessary, honeycombs are removed, we prepare the
countertop for pouring. As you can see, after milling,
the countertop moved a little, so we press it around the
entire perimeter with clamps and apply silicone
around the perimeter. Yes, yes, I know that it would be
easier to cut the end off straight, and then it would take less silicone
and the work would be done faster, but we are not looking for easy ways.
Therefore, we have what we have. And finally, using the technology
patented by me, we finger in a circle. For the first layer, as well
as for the subsequent ones, I took the “Crystal Epoxy”
compound from Artline, since the fill layer is small,
and this compound cures, or rather it would be more
correct to say it polymerizes, i.e. turns into a
polymer, in just a day, which is very convenient for
layer-by-layer work, as in this case. I slightly tinted
it in blue colour. As a result, this layer should
fill the volume by 60-70%. In the meantime, these 60-70%
are converting into polymer, we are engaged
in the underframe. The underframe will be
unpretentious, also made of oak. We file it in the right
size, at the right angle, make a selection, gluing, in
general, everything is as usual, Andrey was mainly
engaged in all this, so if you have any questions,
you are welcome to his Instagram. The legs will be attached in
such a simple and reliable way. We attach these mortgages on a
pocket hole joint using a Kreg jig. In the meantime, the first layer has cured,
I mix the same compound. The second layer should
be opaque, but thin, so that the wires, LED tape and
other communications are not visible, but so that the light from
the tape breaks through. You will understand
a little later. This is why I lightly tint the
resin and add colour powder. In fact, it is a very
fine metallic pigment. And I fill it with a layer
of a couple of millimetres. As a result, in the main
layer, the light will evenly spread and rest against
this opaque layer, so we get the most vivid effect. If we filled the entire layer
with a metallic pigment, then the light would
practically not pass through it and the intended
effect would not work. Since this pigment is
heavier than resin, it has to be lifted from the bottom
periodically, like this. This must be done just
before the resin starts to set, then it will be possible to fix it in the
desired position, which is what I am doing. When the 2nd coat is cured I spill
the countertop with the final 3rd coat. Since in the end the
countertop will be calibrated, part of the resin will
be cut off by the cutter, as a result, the 2nd
layer may be exposed, and gaps may appear,
through which the backlighting elements will be visible,
which does not suit us at all. That's why the final layer is
transparent and we will calibrate it. Before calibrating the countertop, we
cut it to size using a saw with a broach. For the final calibration, we
use just such a cutter from CMT, it does its job perfectly,
and most importantly, it practically does
not chip epoxy, even in such complex fillings. Which is what you
see on the screen. And now the original idea of not cutting to
the end of the honeycomb becomes clear. The next step is to make a
tricky selection with a spiral cutter. After a few hours of CNC operation,
the countertop looks like this. It remains to remove the pile
and do the most interesting. Before laying out and
connecting all the filling, I cover the countertop
with a matte varnish. Considering that this is the inner side,
it would be possible to do without it, but in this way we will slightly
increase the light transmission and, in general, the
product will look neater. And of course, I also cover the front
side with my favourite matte varnish. In order to achieve
the intended effect, we need to build in about
a hundred touch sensors, but we decided to go even
further and strengthen them in order to make the
effect even cooler. Then we make a
hundred aluminium rings, on which the address
tape will be glued. They will also play the
role of a radiator for cooling. As you can see, all
the materials at hand and an old pipe of a
suitable diameter are used. In the end, we have a hundred aluminium
rings, a hundred reinforced sensors, and a week of soldering
and assembly time. I ordered all the electronic
components in our country, I leave links in the
description of the video. Special thanks for
the prompt delivery, I can safely
recommend this store. The whole circuit
will work on Arduino, I don't really understand
all this electronics, that's why Lyosha
appeared in our team. He made all the
“stuffing” for this project, thanks a lot to him. Thanks to
him, our projects reach a new level. For all questions in the development of
various devices based on microcontrollers and analogy systems, you can write to him,
you will find the link in the description. As a result, the project took
about a month of daily work. Of course, we are interested in
creating just such complex projects. For obvious reasons, this will be
possible only thanks to your support, if such videos gain views,
they will appear regularly, so everything is in your hands. Like, repost and comments help
to promote the video very well. Thanks for watching and catch
positive attacks from the Axe.
